Setting range: 0.00Hz/s – P00.03 (the max. 
frequency) 
After the power loss of the grid, the bus voltage 
drops to the sudden frequency-decreasing point, 
the VFD begin to decrease the running 
frequency at P11.02, to make the VFD generate 
power again. The returning power can maintain 
the bus voltage to ensure a rated running of the 
VFD until the recovery of power.

Note: 1. Adjust the parameter properly to avoid 
the stopping caused by VFD protection during 
the switching of the grid.
